How much resin do I need for a courtyard?
Essential information for accurate coverage and perfect results outdoors.
Wondering how much resin you need for your courtyard? Whether you’re crafting a decorative pebble surface, sealing a concrete area, or planning a unique feature with deep pour resin, knowing the right quantity ensures a flawless, long-lasting finish. This guide will support you in choosing the best resin for your needs and calculating accurate volumes for a range of outdoor applications.
Why Accurate Resin Calculation is Crucial for Courtyard Projects
Courtyard projects succeed when the correct amount and type of resin is used to match your desired finish—be it decorative, permeable, or protective. Proper calculation prevents waste, saves money, and guarantees a resilient and attractive result, especially given the demands of the UK climate.

Comparing Resin Systems for Courtyard Coverage
When selecting a resin system, consider your surface type, desired thickness, and aesthetic goals. Here’s a quick comparison to help you match your use case:
- Decorative pebble or gravel surface: Opt for “Trasparente” – Epoxy Binder for Coloured Pebbles and Grits or “Polirock” – Polyurethane Binder for White Stones (white stones).
- Sealing and protecting concrete: Use “Resinstone”.
- Permeable courtyard floors: “Flowstone” kit offers a complete solution with clear area-based calculation guidance.
- Deep pour features or artistic inlays: Choose “EpoxyTable 5-Five” (for up to 5cm) or “Epoxytable 10-Ten” (for up to 10cm).
For most pebble binder applications, estimate the resin quantity as about 3% of the total stones’ weight (e.g., 15kg stone per m² per cm thickness). Always consult product-specific guidance for exact ratios.

How to Calculate the Resin Quantity You Need
Every courtyard is unique, but you can calculate requirements using these general steps:
Step 1: Measure the total surface area — Multiply the length and width of your courtyard in metres for the total area (m²).
Step 2: Decide on thickness — For pebble finishes, 2-3cm is standard; for concrete sealing, one thin layer suffices; for artistic deep pours, check the project’s dimensions and depth.
Step 3: Choose your system
- For resin-bound stones, such as with “Flowstone”, “Trasparente” or “Polirock”, use about 3% resin binder per weight of aggregate. Example: For 10m² at 2cm thickness, total stones ≈ 300kg (10 × 2 × 15), so resin needed ≈ 9kg (300 × 0.03).
- For concrete sealing with “Resinstone”, coverage depends on substrate absorbency. Follow on-package rates for each coat.
- For deep pour projects using “EpoxyTable 5-Five” (up to 5cm thick) or “Epoxytable 10-Ten” (up to 10cm), calculate the volume (area × thickness) and check the product’s mixing guidelines to determine total litres or kilograms required.
Each product page provides calculators and step-by-step guidance to support your planning—especially for “Trasparente” and complete kits like “Flowstone”.
Expert Tips for Flawless Courtyard Resin Application
Preparation is key: Ensure bases are clean, dry, stable, and absorbent (for sealers). Outdoor installation is best in mild, dry weather (avoid freezing/humid conditions).
Choose the right product: For coloured aggregates, opt for “Trasparente”; for white stones, use “Polirock”; for concrete, “Resinstone” is ideal.
Mix thoroughly: Always mix resin and hardener in the manufacturer’s recommended ratio, blending vigorously for a uniform finish—especially important for deep pour solutions like “EpoxyTable 5-Five” and “Epoxytable 10-Ten”.
Work efficiently: Each system’s working time and curing speed varies. Plan mixes so you never run short mid-application.
Our range covers all skill levels, with clear application guidance for each kit. For DIYers, kits like “Flowstone” include step-by-step instructions. For professional results, trust system-specific products from categories such as pebble floors.

Frequently Asked Questions
What is the best resin system for white or coloured stones in my courtyard?
For white stones, the “Polirock” – Polyurethane Binder for White Stones is ultra-clear and prevents yellowing. For vibrant or natural-tone aggregates, “Trasparente” ensures a crystal-clear, UV-resistant finish.
How do I calculate how much resin and aggregate are required for my courtyard?
Estimate the area (m²) multiplied by desired thickness (cm). Each cm Layer: 15kg aggregate per m². Resin needed is around 3% of total stone weight.
Can I use resin systems on compacted soil as well as concrete bases?
Yes. For light traffic, resin-bonded stone can be installed directly on firmed soil (about 2cm thick). For heavy use or vehicle access, a reinforced concrete base or grid is recommended for stability.
Is DIY application possible for permeable resin pebble courtyards?
Absolutely. Products like “Flowstone” include everything needed with detailed instructions. For larger surfaces, a cement mixer aids even mixing.
When do I need a polyurethane rather than an epoxy binder?
For white stones, polyurethane such as “Polirock” prevents yellowing. For coloured stones, epoxy binders like “Trasparente” are optimal.
What if my project includes deep resin detailing or seating?
Use “EpoxyTable 5-Five” for pours up to 5cm and “Epoxytable 10-Ten” for larger, thicker elements, ensuring the calculation matches your feature’s volume.
Can "Resinstone" be used to bind gravel or only on concrete?
“Resinstone” is designed only for concrete or absorbent substrates. For binding and stabilising gravel, choose a purpose-made stone binder.
